A portion of the plow beam or standard of the plow is indicated bydotted lines in Fig. l at A. B indicates the land-side,-C the frog orbottom of the plow, and Dy the mold-board. The frog, mold-board andland-side may be secured together, in the manner indicated, or in anyother suitablel way. T indicates a bracecommonly eniployed forconnecting the upper end ofV the frog or bottom block of the plow lwiththe mold-board. A brace E is attached to the upper end of the land-sideand it is attached to the mold-board at F. This brace serves to hold themold-board and land-side in proper relation and to withstand strains.The brace has an end e projecting beyond the edge of the inold-board andthis projecting end lof the brace is slotted, as indicated at e', and asshown in Fig. 7 the walls on the opposite sides. of the slot are beveledor inclined, as shown at e2. To the inside of the mold-board is attacheda bed-plate G to which the operating lever is o connected. Thisbed-plate may be attached to the moldboard by a bolt (/and also by abolt g', which, as shown in Fig. 7, is carried by the mold-board andextends through an arm g2 on the lower' or inner end of the plate. Thisarm is raised from the mold-board sufficiently to allow the brace E toextend beneath it, and the bolt g passes through the brace and serves tohold its lower portion securely in place. Y

f The operating lever H is pivotally connected at 7Ly to a standard Irising from the bed-plate. This standard is bifurcated, as shown in Fig.3, and the lever TI extends between the two members of the standard. Oneof these members is provided with a stop 7L (Fig. 3) which limits theinward movement of the lever. As shown in Fig. l the standard I isJformed Vwith an enlargement i at the side of the lever H which in ameasure prevents sidewise movement of the lever. To the lever H isattached an arm l which is bent at right angles, as shown, and then bentagain to form a part j parallel with the inner portion of the lever Hand this part y' isV formed with a bent end j which bears against abrace K 'secured tothe bed-plate. This brace has a curved surface, asindicated, against which the part j bears, and the arrangement is suchthat as the lever is turned on its pivot it is prevented from sidewisemovement, the strain on the lever being partially taken by the arm J andthe brace K'. V

The connecting rod L is `adjustably secured to a sleeve M, pivotallyconnecting to the lever H and the arm J at m. It will be observed thatthe end of the rod is threaded and it engages ak tapped portion Vof thesleeve so that the rod may be adjusted end- Q. The finger Q-is firmlyconnected with the plow share at g and it is bent so as to embrace theedge portion of the frog or block C and to also' bear at as against theinner face of the land-side portion of the frog. `When the plow share isdrawn into place the iinger overlaps the adjacent edge portion of thefrog or block and also bears against the land-side portion of the frogin such manner as to hold these parts of the plow firmly connected.V Theprojection P may be in the form of a bolt p attached to the share andcarrying al washer 79 and llock nut 292.' The slotted end'of the brace Eengages this projection, in the manner clearly shown in the drawings. Byforming the slot e with inclined walls c2, a tight connection isafforded between the brace and the share. The frog C is formed with aslot c to receive the projection N.

Details of the projection more clearly in Figs. t, 5 and 5a. A thimblen, having flattened sides n and agthreaded opening n2, is secured to theplow share by a screw 05,3 whichA extends through the thiinblev andcarries a lock nut n4. The thir'nble is formed with inclined surfaces a5sloping from their outer ends inward toward the central portion of thethimble and adapted to N are shown to the lever so as to move it to theposition j shown in Fig. 2, by dotted lines, the looped end of the rodwill engage the inclined survfaces n in such manner as'to firmly drawthe plow share into true position and firm connection with themold-board and frog and the share will. be held in this -positionaslongas thelever is in the position shown in Fig. 2, the point 'of connectionbetween the lever end of the rod being below the axis about which thelever turns.

' It will be observed that the thimble n has fiat opposite sides and istherefore adapted to receive a wrench which may be used for tightlyfastening the thimble on the screw n3 and for tightening the connectionshould it tend to become loose. 7

By reference to Fig. l it will be observed that the connectingrodtightly holds the share in place when the lever is in the positionshown by full lines in Fig. 2. lVhen the lever is turned to the positionshown by dotted lines in Fig. 2 the connection is loosened and at thesame time if the lever is quickly operated the rear end Z of the loop`will strike against the projection N and will cause the share toseparate from the moldboard, frog and land-side.

In plows of the kind to which my invention relates, it is extremelyimportant that not only the share be made readily detachable but that itshould be firmly held inV and a detachable share, and means forconnectingthe share with the frog, the moldboard and the land-side,comprising a projection on the share adapted to enter the slot in thefrog, a connecting rod having an elongated loop engaging saidprojection, a bracket secured to the mold-board and carrying abifurcatcd standard, a brace on the bracket, a lever pivotally connectedVwith said standard and providedwith an arm engaging the brace,` and aconnecting rod adjnstably connected with the lever and having a loopedend engaging a projection on the share. i

2. A plow, comprising a frog, a moldboard and a detachable share, andmeans for connecting the sharewith the frog and mold boa-rd, comprisinga projection on the share, a connecting rod having a. looped endengagsaid projection, a lever connected with inoth rod, a bed-plateattached tothe moldboard, a bii'urcated standard carried by thebed-plate to which the lever is pivotally connected, an extension on thestandard for bracing the lever and a stop on the standard for limitingthe movement of the lever.

In testimony whereof I have hereunto subscribed lmy name.
